COVID-19 Confirmed Cases Time Series (US)
COVID-19 Confirmed Cases Time Series (US)
Time series data visualizations of the progression of COVID-19 within the United States were created beginning March 21st, 2020. Raw data was sourced from the Johns Hopkins Center for Systems Science and Engineering (CSSE) data repository found at this link.
Data visualizations are updated daily following the public release of new raw data, and typically go live between 21:00 and 22:00 EST. All raw data records are publicly available from CSSE under the data folder titled csse_covid_19_daily_reports. Time series data used in the generation of these figures consist of confirmed case reports from the contiguous US as well as Alaska and Hawaii. Washington DC cases are included in the data. All US cases registered under territories, cruise ships, and evacuees are excluded from the final data.
Visualizations are generated using total confirmed cases and do not account for patients who have recovered or died from COVID-19. Total confirmed case data is presented as four measures: Daily Percent Increase, 72 Hour Percent Increase, Total Confirmed Cases, and Total Confirmed Cases Per 100K Individuals.
Due to the changing nature of these data please pay close attention to the heatmap scales and bar chart axes when viewing an individual figure. As confirmed cases increase, scales and axes will also increase and should be considered when comparing multiple figures across the time series.
Daily Percent Increase in Cases
These data illustrate the daily percent increase in the total number of confirmed COVID-19 cases by state. Daily percent increase measures the difference between the confirmed case total of the current day to the prior case total and expresses this difference as a percentage of the prior case total. The US heatmaps (left) show the daily percent increase within a state as a red color gradient where darker red indicates a greater percent increase. Bar charts (right) illustrate the ten states with the highest percent increase in COVID-19 cases between the 24 hours of measurement. It is important to note that daily percent increase is strongly influenced by the availability of COVID-19 testing and the prior number of confirmed cases within a state. Sudden spikes in percent increase on a given day may not necessarily reflect an increase in disease incidence, but rather an increase in the availability of testing.

72 Hour Percent Increase in Cases
These data illustrate the 72-hour percent increase in the total number of confirmed COVID-19 cases by state. These data show the percent increase in total cases by state over a 72-hour period expressed as the date range indicated by the specific figure. The US heatmaps (left) show the 72-hour percent increase within a state as a red color gradient where darker red indicates a greater percent increase. Bar charts (right) illustrate the ten states with the highest percent increase in COVID-19 cases between the 72 hours of measurement.

Daily Confirmed Cases
These data illustrate the total confirmed COVID-19 cases by state. Total confirmed cases are comprised of all cases that have been validated by an approved laboratory test to meet the criteria for COVID-19 diagnosis. The US heatmaps (left) show the total cases per state as a red color gradient where darker red indicates a higher number of confirmed cases within the state. Bar charts (right) illustrate the ten states with the highest number of confirmed COVID-19 cases at the point of data publication.

Cases Per 100k Population
These data illustrate the number of confirmed COVID-19 by state as the number of cases per 100,000 individuals residing in that state according the US Census Bureau’s 2019 July population estimate. The US heatmaps (left) show the cases per 100k individuals within a state as a red color gradient where darker red indicates a higher number of cases per 100k. Bar charts (right) illustrate the ten states with the highest number of cases per 100k individuals at the point of data publication. State population data was obtained through the US Census Bureau website at this link.
